550MHz Differential Twisted-Pair Driver
The EL5177 is a high bandwidth amplifier with an output in
differential form. It is primarily targeted for applications such
as driving twisted-pair lines or any application where
common mode injection is likely to occur. The input signal
can be in either single-ended or differential form but the
output is always in differential form.
On the EL5177, two feedback inputs provide the user with the
ability to set the device gain (stable at a minimum gain of 1).
The output common mode level is set by the reference pin
(REF), which has a -3dB bandwidth of 110MHz. Generally,
this pin is grounded but it can be tied to any voltage
reference.
Both outputs (OUT+, OUT-) are short circuit protected to
withstand temporary overload condition.
The EL5177 is available in the 10 Ld MSOP package and is
specified for operation over the full -40°C to +85°C
temperature range.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
